In AFFE_MODELE You can declare 4 different element types:
2D_DIS_T
2D_DIS_TT
DIS_T
DIS_TR

This means spring element for 2D- / 3D-model and having only translational or also rotational DOFs.

in AFFE_CARA_ELEM the meaning of CARA='K_T_D_L' is:
K: stiffness matrix (not mass or damping)
T: only translational
D: diagonal matrix (no coupling between X- und Y-stiffness)
L: spring is based on a line element

An alternative to L is N: it needs no line element, but the springs are connected between a Node and the (fixed) environment.

Alternativ to T is TR

Alternativ to D is leaving out D. example: CARA='K_T_L'

And so on

As is clear (I hope) from Your input to CARA=' ' it depends how many values You must input at VALE=(0.25,0.25,...

In the outlined example, 2 values are necessary which have the meaning of X- and Y-stiffness of a line-based spring element in a 2D-Model

The error can be see on the file attached.
What it is mean?
Is there someone to explane me how I can import a file .unv and solve it without using Salome to create .med file?

I lunch the simulation but before finish all appare an error.
In file attched there is all file used to make this simple example.
Can some one help me and explane how the simulation is stopped?
